MONUMENT FOR MARKING LINES AND CORNERS OF LAND SURVEYS, 8w.

SPECIFICATION forming part of Letters Patent No. 241,592, dated May 17,188 1.

Application filed April 14, 1881. (No model.)

To all whom it may concern:

Be it known that I, JACOB B. BAUSMAN, a citizen of the United States,residing at Minneapolis, Hennepin county, State of Minnesota, haveinvented a' new and useful Monument for Marking Lines and Corners ofLand Surveys, or the boundaries of areas or parcels of land or parts ofthe earths surface, of which the following is a specification.

The object of this invention is to furnish a durable and conspicuousmonument or landmark that is not liable to be blown or Washed away byordinary wind or rain storms, or removed or destroyed by grazing orburrowing animals, or destroyed by fire, or injured or removed hy theaction of frost.

My invention consists in forming the monument or landmark of sheet orcastmetal in the shape ofa frustum ofa hollow cone and providingit withperforations, for the purposes hereinafter mentioned.

Figure 1 is an illustration of the blanks of sheet metal from which themonument is formed. Fig. 2 is a view in perspective of the monumentcomplete. Fig. 3 is a top View of the same.

A designates a blank, constituting one half of the frustum of a cone ormonument, and A the other half of the same. These, when properly rivetedtogether, form the frustum of the hollow cone B.

I do not limit myself to forming the monument in sections, as it isobvious that it can be formed in a single blank or sheet, and thustransported, and subsequentlyclosed by riveting a single joint; or themonument maybe made entire of cast metal.

a indicates perforations, of any desired size i or in any desirednumber, for purposes described as follows: first, to render the monumentuseless as a conduit, thereby adding to its security against theft;second, to reduce the weight of material without impairing the strengthor durability of the monument; third, to guard against accumulation ofwater within the monument.

1) indicates perforations, of any desired size or number, serving notonly the purposes already mentioned, but they may be so arranged as toindicate the character, location, or ownership of the said monument.

As heretofore stated, I construct my monument or mark of sheet metal,galvanized, and it may consist of two blanks rivetedtogether,

as in Fig. l, or it may be made from a single blank. For convenience andcheapness of transportation, the blanks need not be made up or rivetedtogether until they arrive at the place where they are to be used.

At the point to be marked by the monument it is set or fixed firmly intothe ground, and it may be sunk its entire length, ora portion of it leftexposed to view; or it may be placed in or under a mound of earth orsome other prominent mark or material, the monument itself to be filledwith earth or any other material or substance that may serve to give itstability or aid in future identification of the same.

The advantages of my device are obvious to any one familiar with themanner of marking land -corners or skilled in the art. Its

conical form prevents its sinking by the force i of gravity in soft ormarshy ground. This form also. resists the upheaving force of frost.

I prefer to have the perforations a and b of the device made at thefactory. Other indicating-marks can be readily made with a coldchisel atthe time it is intended to be used, or when the section, township,range, location, or ownership has been determined;

I am aware that cast-metal heads with perforations to receive bolts forholding the letters and figures of designation have been devised; thatthcse are secured to trestles, tripods, or posts, by which they areanchored in the ground; but such is not my invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s

1. A monument for designating townships, ranges, sections, and othersubdivisions of land, boundaries, and ownership thereof, 850.,consisting of a hollow frustum of acone made from one or more pieces orblanks of galvanized sheet metal, or of cast metal, as set forth.

2. A monument for designating the lines, corners, boundaries, andownership of tracts or subdivisions of land, 850., consisting of ahollow frustum ofa cone made from one or more pieces of sheet metal orcast entire, and having the designating-marks and other perforationspunched or cast therein or stamped thereon, as set forth.
